Working on a 3HP 1947/48 MW motor. Removed the cotter pin and the prop nut, but the propeller won't come off! It is stuck. The prop is engaged with the gears, so the only thing I can figure is that the shear pin is bent or something and, as a result, has wedged itself onto the prop. Would anything else cause it to be stuck like this? I can't see any other bolts or screws holding the prop on and the parts diagram I have doesn't show any either.
I don't want to put any more pressure on the prop than I already have trying to remove it for fear it will break. So, what are my options here? Tapping around the prop hub with a mallet? Heating it up with a torch to see what happens? I'm open to suggestions.
